PATENT OFFICE JOHIN O. CABBEY, OF ST. LOUIS, MISSOURI, ASSIGNOB TO CABREY-MORSE ENGINEERING COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI ADJUSTABLE MOUNTING Application filed, April 16,

This invention relates to new and useful improvements in flexible mountings or supports for motors and the like, the objects of the invention being to provide a mounting adapted to have secured thereto a motonor similar apparatus and having a single line of supporting contact with the base, said line of contact being preferably formed by a resilient member which prevents the transmission of the vibration and noises, incidental to the operation of the apparatus sup ported by,the mounting, to the base or other stationary part supporting said mounting.

Qther objects of the invention are to provide a mounting having yielding points of engagement between the stationary or rigid base and the mounting or plate receiving the motor, said attaching or interengaging means being adjustable to regulate the tension applied to said plate and permit tilting thereof with theresilient member as the axis.

' Further objects of the invention are to provide a simple form of mounting wherein the direct contact between the base and the plate carrying the motor or other apparatus ings, in which- Figure 1 is a side elevational view of the mounting showing the motor in dot-ted lines.

Figure 2 is a top plan View of the mounting, partly broken away. j

Figure 3 is a transverse cross section of a modified form of supporting connection between theplate and the stationary base.

Figure 4 is a transverse detail cross section showing still another modified form.

Referring by numerals to the accompanying drawings, .10 indicates a plate which is adapted to receive a' motor or similar device 11. Plate is'provided with apertures 12 1926. serial No. 102,494.

for rece'ivingsuitable fastening devices for attaching the motor in position thereon.

The underside of plate 10 is provided with a transversely disposed downwardly pre sented seat 13 for receiving the upper edge of a strip 14 of resilient material, such as rubber. The loweredge of this strip is seated in a seat15 formed in a stationary base 16. Seat 13, which is formed by providing two parallel ribs 17, is disposed preferably equidistant from the ends 10 of plate 10 but may be arranged at any point intermediate its ends. Member 14 is of any de'siredthickness and the edges thereof are preferably convex in cross section as indicated at 14 to fit in the concave seats 13 and 15. Base 16 is anchored in position by suitable fastening devices 18. In order to maintain plate 10 in proper position and prevent the displacement thereof with respect to member 11 each end 10 is formed with an open-ended slot 19 through which extends upwardly a bolt 20, the head thereof being located in the base 16. The end of each bolt 20 is threaded and receives a nut 21 which bears against the washer 22. A washer- 23 is loosely placed on each bolt 20 and bears against the corresponding slotted end 10*.

A coiled spring 24 is interposed between each pair of washers 22 and 23 and exerts its influence against the respective end 10, thereby maintaining plate 10 under spring pressure in engagement with resilient member 14. The tension of springs 24 is regulated by turning nuts 21 in proper directions and the tension of said springs can be adjusted independently of each other whereby said mounting may be used as a belt tightener when employed in conjunction with the motor operating a belt drive.

A sleeve 25 of rubber or other suitable insulating'or resilientma-terial is slipped over the shank of each bolt 20 and prevents contact between plate 10 and said bolts '20. \Vashers 23 may also be formed of insulating material such as hard rubber or fiber, thus completing the electrical insulation of motor 11 and platelO from base 16.

The vibration and other noises produced by the operation of the motor are absorbed by the resilient member 14 and springs24 and are thus prevented from being trans- I mitted to the rigid base 16 or other stationary support. Furthermore, the tension of springs. 24 holds plate 10 under pressure to, prevent excessive vibration of said plate and at the same time form'a yielding connection between said plate and the rigid base.

In the modified form Shown in Figure 3, mounting plate 10 is provided with-a do wardlypresented rib 26 preferably formed by securingan angle iron 27 to 3211c underside of 1 said plate 10". Base 16 has a anged thereon 'a' resilient member 27- provided with a V- shaped groove 28 which forms a seat for receiving rib 26. The edge of rib 26 is preferv ably rounded as indicated at 26 to fit in the concave seat 28 of groove 28;

In the form shown in Figure 4, a resilient member 29 is formed rectangularin cross section, and plates 10 and base 16 are .ro-

vided with channel-shaped seats 3O an 31,

respectively, presented toward each other for receiving-the edges bf member 29. In this manner, a certain amount of tilting movement, of plate or mounting 10 is permitted'to allow proper adjustment of said plate and the'apparatus supported thereon and-at the same time the resiliency of the member interposed between the plate and the base serves to revent transmission of vibration from sai plate to-the'base. *I claim: a I. A mounting for-refrigerating appara-' tus comprising in combination a base, a strip ofrubber arranged transversely thereon an extending upwardly therefrom, a rigid j mounting plate resting'intermediate its ends side of said plate and extending downwardly and engaging the upper edge .ofi said strip and forming a pivotal mount for said supporting plate, bolts seatedzin saidbase and extending upwardly throu h the o formed in the ends of said ate, w gs 8 :5 justably mounted on the t readed ends of said bolts, and coil springs interposed between said washers and bear-mg on top ,upwardly presented transversely disposed,

rigid-supporting plate arranged thereabove,

a strip 0 rubber arranged on said support tansversely of sa idplate and extending upwardly from said sup ort, means on the underside ofsaid plate or engaging the upper face of said stri whereby said plate-is fulcrumed interme iate its ends on said strip, and tensioning means statlonarily mounted in said support and arranged to each side of said strip and engaging said plate whereby thelatter is 'eldlngly held in balanced po-' sition on sai strip.
